SULPHURIC ACID 98% 25kg
Sulphuric acid is a strong corrosive mineral acid with molecular formula H2SO4.
Sulphuric acid is and important reagent in a large number of processes.
Among the many uses, some of the major applications are as below
⇒ Catalyst and dehydrating agent in many organic chemical manufacturing and petrochemical processes.
⇒ In the manufacturing of detergents
⇒ In the manufacturing of titanium dioxide ( a widely used white pigment ), and other dyes and pigments.
⇒ In the manufacturing of fertilizers mainly phosphates but also zinc, ammonium and potassium sulphates
⇒ In the manufacturing process for a range of plastics.
⇒ Metal processing such as pickling and de-scaling of steel, and non-ferrous metal plating and purification.
It is also used in wastewater treatment processing, and chemical synthesis.
